E0437 needs to be updated to new format

[sophiajt]

From: src/test/compile-fail/E0437.rs

E0437 needs a span_label, updating it from:

error[E0437]: type `Bar` is not a member of trait `Foo`
  --> src/test/compile-fail/E0437.rs:14:5
   |
14 |     type Bar = bool; //~ ERROR E0437
   |     ^^^^^^^^^^^^^^^^

To:

error[E0437]: type `Bar` is not a member of trait `Foo`
  --> src/test/compile-fail/E0437.rs:14:5
   |
14 |     type Bar = bool; //~ ERROR E0437
   |     ^^^^^^^^^^^^^^^^ not a member of trait `Foo`
